All day today I've been playing The Legend of Zelda Ocarina of Time. All because I told my sister that I could beat it in six hours. She challenged me on it and I agreed. As it turns out it takes me eight hours and fifty-one minutes to beat the game (According to the Wii play history). I didn't really think I could beat it that quickly, but I manged to pull it off. Fastest I've ever beaten that game. Terrible way to spend a Sunday, I know, but whatever.
I want to know, what game have you managed to beat quickly and what was the time it took you? Did you really feel like you accomplished anything or was it more like "I can't Believe I just sat here for (x amount of hours)..."?
